What is failure? How do we define it? In the dictionary failure has many meanings, it can be defined as a lack of success or one that has failed. I believe this is too broad a definition and I refer back to some of my previous posts where I talked about success. Success being different for each person means also that failure can be different for different people. I prefer to define failure as a necessary building block on the road to success. Very few people have immediate success when they begin a new venture.
